This kit offers a great way to introduce youngsters 7 to 10 to the joys of birdwatching, with an illustrated field guide and a window-mounted birdfeeder in durable sky-blue plastic. The author and illustrator of numerous nature and gardening books, as well as a teacher of nature classes for more than 20 years, Sharon Lovejoy shares her expertise and her enthusiasm for 34 backyard birds, from the zippy ruby-throated hummingbird to the clever chickadee. The house-shaped feeder, 10 inches tall, features large side openings and a porthole in the back, a generous seed bin at the bottom, and a drop-down front for easy cleaning. It mounts to the window with the two suction cups provided.
